‘The Messenger of Allah, sallallaahu ‘alayhi wa sallam, visited Umm As- Saa’ib (a woman Companion) and said to her: “What is the matter with you, O Umm As-Saa’ib, why are you shivering so violently?” She said: “I have a fever, may Allah not bless it!” The Prophet of Allah, sallallaahu ‘alay- hi wa sallam, said: “Do not curse fevers, because they do away with the sins of the children of Adam just as a furnace does away with the im- purities of iron.”1
